This example visualizes a social network as a node-link diagram, with ten people connected by twelve friendship links. Circles represent each person, with their name displayed as a text label, and arrows on the connecting lines indicate the direction of the relationship. The network is laid out using D3’s `forceSimulation` with link, charge, and collision forces, and users can drag nodes to explore the connections. The SVG rendering uses the `d3.js` v6 library, and the data is loaded from a JSON file containing node and link attributes like person names and relationship types.
